To all whom it may concern:

13eit known that I. Zannox G. Snows,

. citizen of the United States, and resident of the borough ofManhattan. city of New York, in the county -of Xew York and State of NewYork, have invented certain new and useful Improvements in Type-YVritingMachines, of which the following is a specitication.

My invention relates, to typewriti-ng machines and more particularly tothe'type actions of such machines.

\. The main object of my invention is to pxpvide wide and efficientpivot bearings fpr the-type hars andyet employ a large-num- -l is avertical front to rear central sectional kie'w of afront-striketypewritil'ig machine .E'mbodying my invention, only so much of 5 saidmachine heing'shown as is necessary to illustrate the invention in itscmhmhment therein. Fig.- 2 is a fragmentary vertical transversesectional view of the same taken on a line ur-w,o't Fig. 1 and lookingin the direction of the arrow atsaid line. Fig. 3 is'an enlarged(letailside elevation of one of the type bars of the set which ispivoted nearest the back ofthe machine. Fig. is an enlarged detail sideview of one of the type bars of the intermediate, set. Fig. 5 is anenlarged'detail side view of one of the type bars of the foremost set.Fig. 6 is an enlarged detail fragmentary rear view showing a group ofthree bars of thethree different sets. Fig. 7 is anenlarged detailfragmentaryperspective View of aportion of the type bar segment. Fig. 8is a. frag-- mcntary diagrammatic plan view of the type basket,partsheing shown skeletionized.

The frame of the machine comprises a base 1, corner posts 2 and a topplate 3. A suitable carriage (not shown) is mounted on-the top p1ate\andcarries a platen 4 dia- 5 have curved t'nlcrum treads (l which hearagainst a fulcrum plate 7. Each of the key levers is provided with alinger key 8 and is connected by a strap 9 to a restoringspring 10. Asub-lever 11 )ivoted intermediate its ends at 12 to each key lever andis slotted at 13 to receive a fulcrum bar or rod ll that extendstransversely hcneath the system of key levers and secured at its. endsto the frame of the machine. The sub-levers extend upwardly differentdis tances as indicated in Figs. 1 and 2 depending upon the position ofthe type bars with which they are associated. These sulnlcvcrs areconnected to the rear ends of pull links 15 arranged ahove the segment.The forward ends of the links enter slots 1/. 7) and a in the type.liars l6. l7 and l8. respectively. and are pivoted to said bars in Him.3 openings at (7. c and f, respectively. type bars are at ditterent.lengths. t e liars 16 being the hmgest and the i vpc ars 18 being theshortest. The shapes-at th dili'erent type liars are clearly shown in ligs. to .7 inclusive from which it will e seen that the type liars ltlarr-each formed a iih a gooseaicck 19 by which it is cnahlcd to clearthe hangers o"? the shorter tyne hars as shown in Fig. l. The type bars1''? are each likewise, provided with a. Q0054 neck it) whi h. however,shorter than the yonnecks ll) ot the type liars ll". The nccks illol'thc type bars I? likewise nable these type bars to clear the hangersot' the foremost set of type bars 18. Each of the type bars ol the threesets is provided with an upwardly extending projection Theseprojc-ct'im..-.. together with the goes. necks 19 and 20 on the typebars 16 and l"? cnablethe pull links 15h: he connected with the typebars at dil'l'erent. heights as indicated in Fig 1 although thedistances of the points of connections from the. pivots of the.ditl'erent l ars is substantially the same.

Where the-projections 211 are. not required for the per-pose ofeffecting a connection with the links 1' thelcss, to give auniformappearance of the type hars when at rest in the basket. From aninspection of Figs. 1, 2 and 8 it,

t-hey are employed, ncver-- Thus,

will he seen that the various projections 21.-

grannnatically shown in Fig. l. Key levers line a: which cuts the pivotsof the three adjacent type bars (if the center group is at substantiallyright angles to a line drawn from the printing pointy to 'a type 2 ofone of said type bars when at rest'in the basket. This arrangement ismaintained throughout the system because of the mounting of the type barhangers in three sets on .an upright type-bar-segment 22 which isstepped on its rear side to-provide three upright, segmental steppedsecuring faces 23,- 24 and 25 which are concentric and at progressivelyhigher I elevations from the rear to the front of the segment and extendthroughout the length of the segment. The stepped face 23 provides anupright bearing face for a set. of

radially disposed segmentally arranged hangers 26 which are preferablylooped to form securing stems or portions 27 and are spread outwardlytherefrom to form hanger arms 28, perforated to provide bearing openingsfor the trunnion-like pivots 29 of the 'type'bars. In the presentinstance I have shown ten hangers secured to the rearmost" stepped face.23 although this number may be changed at will. The second orintermediate step 24 constitutes an upright bearing face for.anintermediate set of hangers 30 a which may be constructed and arrangedlike a 40 thehangers 26,. although certain of 'these hangers 30 arepreferably provided with offset hanger arms 31 whereas thecompanion armis substantially straight as shown in Fig. 2. This is in orderzto effecta proper relative arrangement of the type bars and hangers of thedifierentsets. There are'sixteen hangers 30 shown in the presentinstance, although this number'may be varied at will. The third orforemost stepped face 25 constitutes anupright bearing face for thehangers 32 of the. foremost set of type bars 18. These hangers may beconstructed like the hangers 26 or some of them may be provided withoff-set arms 31 as desired; and there are sixteen of these hangers shownin the present instance, although this number may bevari'ed.- Thevarious hangers of the different sets have a staggered arrangement aswill be apparent from an inspection of Fig. 2. The segment itself hasopenings 35 (Fig. 7) which extends therethrough fromthe front to therear of the segment for the passage of beaded seouringbolts orscrews 36which )ass through the segment from the front oi the machine andcooperate at their rear threaded ends with tapped holes in scouringplates 37, each of the securing plates preferably cotiperating with twoor more hangers although an individual screw or bolt 36' is provided foreach hanger and extends through the opening provided in the stemthereof. The securing plates 37 have been omitted in Fig. 2 in order tomore clearly illustrate other parts of the structure. By thisconstruction each individual hanger may-receive a radial adjustment andmay also receive a swinging adjustment around its screw 36 as a center,to vary the. point of impact along the printing line without throwingthe type off its feet. The individual hangers are preferably providedwith rivets 38 (see Fig. 6) by which the spread of the hanger arms isdetermined andinaintained; The rivets 38 have likewise been omitted inFig. 2 in order not to obscure pther parts of the structure.

It will be understood that by passing the securing screws through thesegment from the front, where access may be readily had to them from thefront of the machine, I am enabled to readily detach each hanger fromthe segment, the staggered arrangement of the screws affording a. wideseparation and enabling easier access thereto. It vwill thus be seenthat by this arrangement I have provided individual hangers forforty-two type bars each carrying two types 33; and

that by shifting the segment 22 by any suitable case shifting mechanism(not shown) on the bearing balls 34 (Fig; 2) I am enabled to provideeighty-four characters in the machine and yet give to each,type bar anexceptionally wide pivot bearing as indicated in Figs. 2 nd 6. "It willlikewise be observed that the width 'of the system of upright sub-leverscorresponds substantially to the system of type bars and to the systemof key levers at the points where said key levers V are connected to thesub-levers, so that there is a substantially straight line pull on thetype bars without side strain.

Various changes may be made without departing from thespirit and scopeof my invention. i

What I claim as new and desire to secure by Letters Patent, is:

1. In a front-strike ing three adjoining, segmental, upright, stepped,bearing faces; three sets of adjustable, individual, segmentallyarranged, staggered, overlapping, hangers, oneset secured on eachupright, stepped, bearing face of the segment; screws which pass intothe segment from the front of the machine and secure saidhangers inplace,'a separate screw being employed for each ha 'er and each hangerbeing adjustable-aroun the axis of its screw as a center; and typebar's'pivoted to said hangers.
